K3, noise from com cable on SSB?

[Mike Smith VE9AA]

I think I discovered something.  Playing with audio levels on the computer,
I think I have this background tone and pulsing coming from the com port
down to acceptable levels.

I cranked the audio way up in Windows (was at a "2") and it seems to nearly
completely mask this interference/feedback without distortion.

I don't do much SSB, so it'll probably work out.

 

If anyone else has ever experienced this when running their audio through a
computer, I've love to hear from you !

 

Yes, I have the USB cable through a ferrite also.

What are you trying to accomplish by "running audio through a computer?"
Contest message playback?

My Power Point on Grounding, Bonding, and Audio. k9yc.com/publish.htm  
detailed advice for interconnections. The review of USB sound adapters
includes detailed advice on setting levels. The solution to your issues
is very likely within these two pieces.

I think we worked you from N7N during 7QP. Thanks!
